91d7e0c47f arm64: zynqmp: Create fdtfile from compatible string
distro boot expects that fdtfile name is setup for alternative DTB.
Create this file based on the first platform compatible string.
This should ensure that one rootfs can store multiple DTBs for different
boards.
Reflect structure which is used in Linux kernel. It means dtbs are
strored in xilinx folder.

9755e3db8b xilinx: Move zynq_board_read_rom_ethaddr to shared location
Zynq and ZynqMP are sharing similar code and there is no reason to do
code duplication. Move zynq_board_read_rom_ethaddr() to common file for
easier conversion to DM.
Use ZynqMP version that's why also add CONFIG_ZYNQ_EEPROM_BUS to Syzygy
which is only one Zynq board which is using this feature.

ee97a9996a arm64: zynqmp: Add mini mtest configuration
This configuration is useful when you want to run small u-boot and
perform DDR memory test to make sure that DDR is properly configured.
It is use for board bringup because alternative u-boot memory tests is
quite good.
Configuration is running out of OCM.

As is done for others mini configurations 0x80 bytes for variables is
enough and only default variables are stored there.

Alternative memtest is enabled and also 2GB of DDR via DTS files.
Configuration is enabling ZYNQMP_PSU_INIT_ENABLED and include psu_init()
from zcu102 for testing purpose.
In case of size issue this can be moved to SPL configuration as is done
for mini_qspi configuration but it is not a problem now.

1fbca0db5d arm64: zynqmp: Try to enable the first watchdog via aliases
Add support for enabling the first watchdog pointed via aliases.

DT fragment:
	aliases {
		...
		watchdog0 = &watchdog0;
		watchdog1 = &watchdog_lpd;
		...
	};

dm tree fragment for above configuration with patch applied:
ZynqMP> dm tree
 Class    index  Probed  Driver      Name
-----------------------------------------
...
 watchdog    0  [   ]   cdns_wdt    |   |-- watchdog@ff150000
 watchdog    1  [ + ]   cdns_wdt    |   `-- watchdog@fd4d0000
...

dm uclass fragment:
ZynqMP> dm uclass
...
uclass 75: watchdog
0   watchdog@ff150000 @ 7df02f40, seq -1, (req 1)
1 * watchdog@fd4d0000 @ 7df02ff0, seq 0, (req 0)
...

It is visible that index 1 is IP with seq 0 which means that FPD
watchdog (@fd4d0000) is in DT below LPD watchdog (@ff150000).

Till this patch the first watchdog found in DT was used and started
which is not enabling all possible configuration based on user request.

6da4f67ad0 arm/arm64: zynq/zynqmp: pass the PS init file as a kconfig variable
U-Boot needs to link ps7_init_gpl.c on Zynq or psu_init_gpl.c on
ZynqMP (PS init for short). The current logic to locate this file for
both platforms is:

 1. if a board-specific file exists in
    board/xilinx/zynq[mp]/$(CONFIG_DEFAULT_DEVICE_TREE)/ps?_init_gpl.c
    then use it
 2. otherwise use board/xilinx/zynq/ps?_init_gpl.c

In the latter case the file does not exist in the U-Boot sources and
must be copied in the source tree from the outside before starting the
build. This is typical when it is generated from Xilinx tools while
developing a custom hardware. However making sure that a
board-specific file is _not_ found (and used) requires some trickery
such as removing or overwriting all PS init files (e.g.: the current
meta-xilinx yocto layer).

This generates a few problems:

 * if the source tree is shared among different out-of-tree builds,
   they will pollute (and potentially corrupt) each other
 * the source tree cannot be read-only
 * any buildsystem must add a command to copy the PS init file binary
 * overwriting or deleting files in the source tree is ugly as hell

Simplify usage by allowing to pass the path to the desired PS init
file in kconfig variable XILINX_PS_INIT_FILE. It can be an absolute
path or relative to $(srctree). If the variable is set, the
user-specified file will always be used without being copied
around. If the the variable is left empty, for backward compatibility
fall back to the old behaviour.

Since the issue is the same for Zynq and ZynqMP, add one kconfig
variable in a common place and use it for both.

Also use the new kconfig help text to document all the ways to give
U-Boot the PS init file.

Build-tested with all combinations of:
 - platform: zynq or zynqmp
 - PS init file: from XILINX_PS_INIT_FILE (absolute, relative path,
   non-existing), in-tree board-specific, in board/xilinx/zynq[mp]/
 - building in-tree, in subdir, in other directory

2882b39d56 arm64: zynqmp: Setup the first boot_target at run time
Detect mmc alias at run time for setting up proper boot_targets sequence.
The first target has to correspond with boot mode.

The purpose of this patch is to get rid of CONFIG_ZYNQ_SDHCI0/1
parameters in full U-Boot.
Unfortunately this patch can't remove it because there is missing
mmc implementation for SPL_DM_SEQ_ALIAS.

Also xilinx_zynqmp.h only setup boot commands for mmc0 and mmc1.
It means using aliases with higher number won't work. But switching
between mmc0 and mmc1 should work properly.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

01c42d3d74 xilinx: zynqmp: Use strlen only if env_get doesn't return null
Add check if boot_targets exists in environment and then
generate new_targets env accordingly. Performing strlen on
null address causes it to fail with exception if isolation
is enabled with DDR address zero as secure. It works with out
isolation enabled as zero is valid address but it may lead to
junk values in boot_targets.
This patch fixes the issue by checking return value of env_get
so that it generate boot_targets properly.
